Overview

The Operations Research and Financial Engineering (ORFE) department’s intellectual mission is to develop theory and tools in statistics, probability, and optimization to extract meaningful information from data, and to utilize information to make optimal decisions.

Faculty and students contribute to both the foundations of these three disciplines and their applications in areas such as

  • data science and machine learning, including deep learning, large-scale optimization, causal inference, biostatistics, policy evaluation, genomics, networks and graphical models, analysis of high-frequency time series and high-dimensional data;

 

  • decision science, control and learning, including service systems and queues, reinforcement learning, verification and learning of dynamical systems, optimal and stochastic control, robotics and autonomous systems, and large dynamic games.

 

  • finance and social sciences, including risk management, quantification of model uncertainty, optimal investment, mean field games, optimal contracting, econometrics, causal inference, program evaluation, public policy, decision and choice theory, energy and environmental finance, and reliability management of electricity grids.

 

The department ordinarily offers the Doctor of Philosophy (Ph.D.) in Operations Research and Financial Engineering. This program provides a great deal of flexibility for students in designing individual plans of study and research according to their needs and interests. The department is also a major participant in the Master of Finance (M.Fin.) program offered through the Bendheim Center for Finance.

Courses

Courses

In consultation with the director of graduate studies, students develop a specific course plan. During the first year, students complete six courses that emphasize the foundations of the program, probability, statistics, and optimization. Students take at least ten courses while enrolled: the six core courses during the first year, two directed research courses, and two additional advanced-level courses in the second year. 

The following six core courses are required:

  • ORF 522 Linear and Nonlinear Optimization
  • ORF 523 Convex and Conic Optimization
  • ORF 524 Statistical Theory and Methods
  • ORF 525 Statistical Foundations of Data Science
  • ORF 526 Probability Theory
  • ORF 527 Stochastic Calculus

In addition, at least two advanced courses and two semesters of directed research (ORF 509 and ORF 510) are completed under the direction of a faculty adviser in the student's area of interest by the end of the second year in preparation for the general examination.

Additional pre-generals requirements

Additional pre-generals requirements

Research Adviser
Students ordinarily match with an adviser by the end of the first year of study to begin research in preparation for the general examination. No student may enter the second year without a research adviser of record. Students are expected to identify a faculty adviser in the ORFE department. If a student receives permission to work with a faculty adviser who is not a member of the ORFE department, the student must also have a co-adviser who is on the ORFE faculty and is seriously involved in co-advising the student.

Qualifying Examination
Each student must satisfy qualifying requirements. Qualifying exams are offered in September of the student’s second year. 

Each student must satisfy qualifying requirements. Qualifying exams are offered in September of the student’s second year.  A student who obtained a grade of A- or better in 4 of the six required classes will be exempt from the qualifying exams. If this is not the case and the student obtained a grade of A- or better in at least 2 of the six required classes, the student will meet with the DGS to decide which exams must be taken to satisfy the requirements. The optimization exams are based on ORF 522 and ORF 523. The statistics exams are based on ORF 524 and ORF 525. The probability exams are based on ORF 526 and ORF 527. If a student received fewer than 2 A- or better grades in the 6 first-year classes, they may not take qualifying exams, and their Ph.D. candidacy ends.

The qualifying exams shall not exceed 90 minutes per class, and are administered by 2 ORFE faculty, who will provide the student with the exam questions at least two hours before the examination begins. The examining faculty will decide if the qualifying exam will be written or oral. The results of the qualifying exam(s) are determined by a vote of the faculty. Additional information related to the preliminary examination can be found in the graduate student handbook.

General exam

General exam

ORFE students take the general exam in April or May of their second year. By the end of the Spring semester, students should have met the qualifying examination requirements, have taken and passed ORF 509 and ORF 510, and have passed with a B+ or higher grades two advanced classes. The student must have shown adequate progress in research, and an acceptable level of understanding of their area of specialization.

The general exam consists of two parts, a written and an oral part, both covering the student’s primary area of specialization.  The written part requires taking and passing, with a B+ or higher grade, two approved advanced classes at the graduate (500) level beyond the 6 core classes counted for the Qualifying Exam. These two classes must be approved by the student’s adviser and the DGS.

For each student, an examining committee is selected by the student and adviser. The committee will be approved by the Director of Graduate Studies. Normally, the committee members comprise the student’s adviser(s) and two additional ORFE faculty or associated faculty. The committee will administer the oral exam, evaluate the student’s performance in research and overall knowledge of their field, and make a recommendation to the department faculty. A departmental faculty vote determines the final outcome. The oral exam may be up to 3 hours in length. The general examination committee may ask questions related to the research and the student’s area of specialization.   

Qualifying for the M.A.

Qualifying for the M.A.

The Master of Arts (M.A.) degree is normally an incidental degree on the way to full Ph.D. candidacy and is earned after a student successfully passes the general examination. It may also be awarded to students who, for various reasons, leave the Ph.D. program, provided that these requirements have been met. To be considered for the MA degree, students must fulfill all the first and second year Ph.D. requirements except for passing the General Exam.

(ORF 522, 523, 524, 525, 526, 527, Two advanced courses, ORF 509, ORF 510)

Teaching

The department has a teaching requirement of at least a full Assistant in Instruction (AI) assignment or two half AI assignments potentially beginning in the fall of the student's 2nd year depending on the department's teaching needs. Requirements for teaching include: 

  • Passing the English Language Proficiency Exam by August after the first year of study (if applicable).
  • Attending the mandatory AI Orientation in fall of the 2nd year of study

Dissertation and FPO

Dissertation and FPO

Upon completion and acceptance of the dissertation by the department, the candidate will be admitted to the final public oral (FPO) examination. The committee of examiners for the FPO must consist of no fewer than two current ORFE faculty members, and the 2nd thesis reader should also be a current ORFE faculty member. The Ph.D. is awarded after the candidate’s doctoral dissertation has been accepted and the final public oral examination sustained.

Additional information related to the FPO can be found in the graduate student handbook

Additional requirements

Responsible Conduct in Research (RCR): All Ph.D. candidates are also required to take EGR501 before the end of their second year. This is a half-semester course that will educate graduate students in engineering in the responsible conduct of research. The lectures provide theoretical background information as well as case studies about ethics in day-to-day research situations, publishing and peer-reviewing, student-adviser relationships, collaborative research, as well as in the big picture and considerations of long-term impact. The course is graded on a pass/fail basis.
